MUSIC-SEATCHEL.

SPECIFICATION forming part of Letters Patent No. 726,119, dated April 21, 1903. Application filed November 11,1902. Serial No. 130,2579. (No model.)

To all whom it may concern.-

Be it known that I, RUDOLPH ERNEST TROG- NITZ, a citizen of the United'States, and a resident of San Diego, in the county of San Diego and State of California, have invented a new and Improved Music-Satchel, of which the followingis afull, clear, andexact description.

bag or satchel in which the papers or sheet music may be placed or kept in a'fiat condition-that is, witho ut rolling or folding them.

A further object "is to provide the bag or satchel with flaps or portions which may be readily adjusted to permit any number of sheets to be added'or removed from the bag, yet retain those therein snugly and tightly in position.

With these and other objects of a like nature in view the invention consists in the peculiar construction, combination, and arrangement of parts,as will be hereinafterfully described in this specification,illustrated in the accompanying drawings, and set forth in the appended claims.

While I have herein shown and described my preferred manner of constructing a satchel embodying my improvements,it will of course be understood that I do not wish to limit myself to the precise details illustrated herein, as modifications with respect to the minor details can be made without departing from.

the spirit of the invention or sacrificing any of the advantages thereof,

Reference isto be had to the accompanying drawings, forming a part of this specification, in which similarcharacters of reference indicate correspondin'gparts in all the figures.

Figure 1 is a perspective view of a satchel embodying my improvements, such satchel being shown' in closed or folded position. Fig. 2 is a similar view showing the satchel opened and illustrating the retaining-flaps, and Fig. 3 is a central sectional View taken transversely through the satchel in the position shown in Fig. 2.

Referring now to the drawings in detail, the numeral 1 designates the main body portion of a satchel or bag constructed in accordance such as the strap 4, is secured to one of said portions and is adapted to be held in a buckle or like fastening means 5 on the other portion. The materialof one of the folded portions of the bag (shown in the present instance as the'portion 3) is duringthe manufacture of thesatchel provided along its side and bottom'edges with a number of fiaps'or. extensions, as. shown at 6, 7, and 8. 7 They may be secured to' thebag portion inan'yEuitable or preferred manner, .as by stitching, for may even be formedinte'gral with'said portion during the cutting of the body of the bag. These flaps, as will be seen on reference to the drawings, are in the present instance triangular in shape and when opened outward away from the main body portion of the bag extend some distance beyond the sides and one end thereof. A fourth flap, as at 9, corresponding or'similar to the others, is formed of a separate piece of material and is stitched or'otherwise secured along its longer side centrally of the inner face of the main body portion in ,such manner that it may be folded inward toward the othermembers 6, 7, and 8.

Eaclr of [the said triangulanfla'ps has at a. point 1 nearits apex; an "aperture, through which aperture is inserted a wearing eyelet 10. Through these eyelets is adapted to be passed a lacing-string 11, the ends of which are to be tied or knotted together, as at 12. The flaps are cut'tosuchsize that-there is a considerable space between the contiguous sides of adjacent flaps, and when the flaps are all folded inward toward the center and the string is passed through the lacing-eyelets the flaps may be adjusted by said string for the purpose of holding tightly and securely in place any desired quantity of paper, sheetmusic, or the like.

On the interior face of the portion 2 of the satchel is formed, as shown at 13, a pocket for the purpose of providing a supplemental receptacle. A second pocket 14 may be formed on the exteriorsurfaco of the portion 3, such pockets greatly adding to the carrying capacity of the satchel and providing means for the reception of small articles, such as pencils and the like.

Suitable handles 15 are secured to the exterior of the bag, and, as will be seen, the portion 2 is provided with a curved extension or end 16, adapted when the two bag portions are folded to fit over the end of the portion 3 and be secured thereto by the fastening means described.

A satchel constructed in accordance with my invention will be found especially convenient and useful by students and teachers, and in particular is adapted for carrying without folding a large quantity of sheet-music. The flexibility of the triangular flaps permits them to be adjusted to securely retain the contents therein, and the satchel as a whole is very compact and presents a neat appearance.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A satchel comprising a flexible body adapted to be folded upon itself, forming two body portions, four triangular flaps on one of said body portions and adapted to be folded inwardly, the flaps having their inner ends apertured and of a size that when folded inwardly a space will be left between the adjacent sides of the several flaps, and a cord extending through the aperture of each of the flaps, the construction being such that when the flaps are folded inward they may be adjusted by means of said cord for retaining any desired quantity of matter such as sheetmusic, in a fiat, unrolled condition.

2. A satchel, comprising a body having a front portion and a back portion foldable one upon the other, triangular flaps on one of the said portions and adapted to fold over the inner face of the same, each flap having an aperture in its apex and the said flaps being of such a size that when folded inwardly a space will be between the adjacent sides of the several flaps, and a lacing string extending through the apertures of the several flaps.

3. A satchel, comprising a flexible body adapted to be folded upon itself to form front and rear portions, one of the said portions being provided at its end with a. curved extension, and on its inner face with a pocket, four triangular flaps on the other portion of the body and adapted to fold over the inner face of the same, each flap having an aperture at its apex, and the said flaps being of such a size that when folded inwardly the flaps will be spaced apart, and a lacing-cord extending through the apertures of the several flaps.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

RUDOLPH ERNEST TROGNITZ.
